Regret theory and the banking firm: The optimal bank interest margin

This paper examines the optimal bank interest margin, i.e., the spread between the loan rate and the deposit rate of a bank, when the bank is not only risk-averse but also regret-averse. Regret-averse preferences are characterized by a utility function that includes disutility from having chosen ex-post suboptimal alternatives. We show that the presence of regret aversion raises or lowers the optimal bank interest margin than the one chosen by the purely risk-averse bank, depending on whether the probability of default is below or above a threshold value, respectively. Regret aversion as such makes the bank less prudent and more prone to risk-taking when the probability of default is high, thereby adversely affecting the stability of the banking system.     

Exploring the mismatch between credit ratings and loss-given-default: A credit risk approach

It is commonly observed that high grade loans with better ratings are often associated with low recoveries if they default (i.e. with relatively high loss-given-default (LGD)). To address the mismatch problem, this paper proposes a credit risk approach by minimizing LGD for higher rated loans as a risk-rating matching standard in the sense that the decreasing LGD from creditors’ perspective is associated with higher credit rating for the borrower. This standard forces customers’ credit rating of each grade to be optimally determined in correspondence to its LGD, which means the LGD of high grade loans tends to be low. The approach is then tested using three credit datasets from China, i.e. credit data from 2044 farmers, 2157 small private businesses and 3111 SMEs. The empirical results show that the proposed approach indeed guides the way to solve the mismatch phenomenon between credit ratings and LGDs in the existing credit rating literature. By optimally determining credit ratings, the findings derived from this paper help provide a valuable reference for bankers, and bond investors to manage their credit risk.     

银行业市场结构与货币政策冲击——基于异质性银行的模型分析

通过构造货币政策冲击下的贷款市场总体均衡模型,研究在受到资本充足率和存贷比约束的条件下,银行最优信贷决策行为。分析发现,在垄断竞争的银行业市场结构背景下,银行间在价格竞争方面表现出战略互补特征和由此带来的模仿效应。因而,当银行满足资本充足率和存贷比要求时,银行业传导的货币政策信贷渠道是有效的,而当贷款市场中的银行不能满足资本充足率或存贷比要求时,信贷渠道则表现出无效性。     

社会信用文化、金融体系结构与金融业组织形式

本文以银行业绩效为依托,纳入社会信用文化这一新的影响因子,试图在一个更广阔的层面上综合考察决定金融业绩效的各种因素,并尝试在这一过程中探求社会信用文化、金融体系结构和金融业组织形式及其绩效表现之间的内在联系机制。实证结果表明,社会信用文化对金融体系的效率和金融体系结构的选择具有重要影响,而法律传统、政府治理及管理能力也在金融体系结构和金融业组织形式的选择上起着重要作用,并最终影响到金融业运行效率。     

影子银行体系的信用创造：机制、效应和应对思路

本文从金融功能视角,将影子银行体系的范畴界定在发挥了类似于商业银行存款、贷款、结算等功能的三大类非银行金融机构。在此前提下,从金融机构和金融产品视角,重点剖析了前两类金融机构的信用创造机制。同时,提出影子银行体系的信用创造机制对商业银行具有有限替代效应,并在货币市场上产生外部溢出效应。即流动性之谜。最后,基于影子银行体系信用创造机制缺陷,提出从抵押品管理角度入手。在金融市场中建立证券最后贷款人,以规避影子银行体系信用扩张的风险。     

Business cycle fluctuations and household saving in OECD countries: A panel data analysis

We investigate the cyclicality of the household saving to household disposable income ratio for a panel of 16 OECD countries over the period 1969–2012. We find evidence that the household saving ratio is countercyclical. We empirically investigate whether the determinants of saving suggested by a standard buffer stock model of saving can explain this finding. The three main determinants of household saving implied by such a model (i.e., unemployment risk, household wealth and credit constraints) have a significant impact on the household saving ratio while their combined effect completely offsets its countercyclicality. The saving regression results are robust to potential endogeneity of the regressors, to making use of a reduced sample size that leaves out the period of the Great Recession, and to the one-by-one addition of variables suggested by alternative theories that also predict a countercyclical saving ratio.     

Keynes and a post-Keynesian controversy over the effect of debt on income expansion

The paper considers arguments of Robertson (1938) and Asimakopulos (1983) that the Keynesian multiplier expansion of output may be constrained by debt implicitly incurred in the financing of autonomous investment necessary to start the multiplier process. The task of this essay is to show that within the ‘short-period’ and static analytical framework of Keynes, this line of reasoning regarding the adverse effects of debt on multiplier-induced expansions of output is unwarranted. Nevertheless it is concluded that if the Keynesian framework is abandoned in favour of a dynamic framework in the manner of a steady trend rate of growth - a choice dependent on how one conceives of the economy, as inherently static or dynamic - then such arguments have troubling implications. In particular, the dependence of Keynes's approach on credit and hence debt forges links between ‘short-periods' whose distinctness from one another is crucial to Keynes's result.

Toward a non-linear theory of economic fluctuations: Allais's contribution to endogenous business cycle theory in the 1950s

Abstract

In this framework, the existence of a limit cycle is mathematically proved and its existence confirmed by empirical evidence. The mathematical tools are similar to Keynesian pioneering non-linear macrodynamic advances but the theoretical framework is obviously totally distinct. In particular, for Allais, the origin of endogenous cycles is monetary, and explained by the interplay between two key elements: the agents that hold the desired money balances and the banking system that can create money.     

Financial cycle and business cycle: An empirical analysis based on the data from the U.S

In this paper, we first study the relationship between the financial cycle and the business cycle in the time and frequency domain. Then we also explore the interactions and dynamic mechanisms of the financial cycle, the business cycle, real interest rate and exchange rate by the VAR model. The empirical results show that the financial cycle is closely related to the business cycle, especially at medium-term frequencies (8–30 years), the business cycle leads the financial cycle with a high positive correlation. However, the relationship between them is not significant during the Great Moderation at business-cycle (2–4 years). In addition, the financial cycle not only becomes a main driver of real interest rate, the financial cycle and the business cycle, but also serves as an important source of the business cycle fluctuations. In general, our results lay some theoretical foundation for the policy practice of financial and economic stability.     

European Banking Distress and EMU: Institutional and Macroeconomic Risks

Financial stability in Europe has received renewed attention with the advent of EMU. This paper examines whether EU country banking systems are particularly vulnerable to systemic risk. Our approach is to explore episodes of banking sector distress for a large sample of countries, highlighting the experience of the EU. We estimate multivariate probit models linking the likelihood of banking problems to a set of macroeconomic variables and institutional characteristics such as aspects of bank supervision and regulation, restrictions on bank portfolios, and development of the banking system. Given these characteristics, the model predicts a low probability of banking sector distress in EMU countries.

Equity market information and credit risk signaling: A quantile cointegrating regression approach

Investigating linkages between credit and equity markets, we consider daily aggregate U.S. CDS spreads as well as well-chosen equity market and implied volatility indexes over ten years. We describe such robust (to spurious correlation) relationship with the quantile cointegrating regression approach. Such approach handles extreme quantiles/CDS values and their behavior with respect to the equity market's influence. Heteroskedastic patterns such as time-varying variance, but also autocorrelation, skewness and leptokurtosis are captured. Thus, the sensitivity of aggregate CDS spreads to equity market price and volatility channels is accurately measured across quantiles and spreads. Such quantile-dependent sensitivity exhibits asymmetric responses to equity market shocks. A sub-period analysis investigates potential regime shifts in estimated quantile cointegrating regressions. Quantile cointegrating coefficients vary over time and quantiles, and exhibit different magnitudes across sub-periods and spreads. Therefore, the relationship is unstable over time. We also propose a scenario analysis and risk signaling application for credit risk management prospects. Under specific risk levels, credit risky situations are described conditional on the equity market's information over time, and related expected aggregate CDS spreads are computed. Estimated conditional quantiles/CDS spreads act as credit alert triggers.     

银行业结构与经济增长

本文运用中国28个省区在1985—2002年间的面板数据,考察银行业结构对经济增长的影响。文章对银行业结构的分析着眼于不同规模的银行在银行体系中的相对重要性,度量指标为中小金融机构的市场份额,即四大国有商业银行之外的其他金融机构的贷款余额占各地区全部金融机构贷款余额的比例。为了克服银行业结构可能存在的内生性问题,文章用1994年启动的国有银行商业化改革的政策因素来构造银行业结构的工具变量。运用双向固定效应模型的估计结果显示,在中国现阶段,中小金融机构市场份额的上升对经济增长具有显著的正向影响。     

Unemployment, credit rationing, and capital accumulation: a tale of two frictions

Summary. This paper develops a model in which two information frictions are embedded into an otherwise conventional neoclassical growth model; an adverse selection problem in the labor market and a costly state verification problem in the credit market. The former allows equilibrium unemployment to arise endogenously while the latter is responsible for equilibrium credit rationing. This structure is used to investigate a theoretical link between the level of unemployment and the extent of credit rationing (and capital formation). The presence of the labor market friction is enough to generate scope for multiple steady state equilibria. The model also generates a large class of endogenous cyclical and chaotic dynamical equilibria. Development trap phenomena may also appear.

The characteristics of a monetary economy: a Keynes-Schumpeter approach

Mainstream monetary theory considers money only as an instrumentmeant to facilitate trading without having any effect on incomeor on the evolution of the economic system. The aim of thispaper is to elaborate a monetary theory capable of supportingthe thesis of money non-neutrality based on the arguments developedby Keynes and Schumpeter. The synthesis of the theories of thesetwo great economists will be formulated starting from the twopoints which are common in the views of Keynes and Schumpeter.First, in contrast with mainstream theory, Keynes and Schumpeterstate that the diffusion of a fiat money induces a radical modificationinto the way in which the economic system works. Second, whenKeynes and Schumpeter describe the reasons why money and financialaggregates are not neutral, they highlight the fundamental roleof the credit market and of banks; in contrast with the mainstreamtheory, they do not consider the credit market as the mirrorimage of the goods market.     

金融业监管当局的治理:对两套标准的介绍和对中国银行业监管治理的初步分析

银行业监管当局良好的治理安排,有助于通过内部"X"效率的改进,促进银行业监管效率的提高.中国银行业监管需要引进先进的监管理念、监管技术,也同样需要基于国际经验,结合国情构建银行业监管的良好治理.后者甚至可能更具基础意义.本文在就两套监管治理评价标准介绍的基础上,对中国银行业监督管理委员会成立后,中国银行业监管治理进行了初步分析.总体结论是中国银行业的监管治理已具备了良好监管治理的形式,实施良好监管治理前提条件的缺失或不足抑制着良好监管治理的实施,成立独立银行业监管机构只是完善银行业监管体制改革的一个良好开始.推动良好治理的实施在某种程度上是银行监管机构能力之外的事,国家仍需在此方面做出努力.     

Limited participation,private money,and credit in a spatial model of money

Summary. The purpose of this paper is to explore the implications of private money issue for the effects of monetary policy, for optimal policy, and for the role of fiat money. A locational model is constructed which gives an explicit account of the role for money and credit, and for limited financial market participation. When private money issue is prohibited, there is a liquidity effect as the result of a money injection from the central bank, but this effect goes away when private money is permitted. Private money issue changes dramatically the nature of optimal monetary policy. With private money, fiat currency is no longer used in transactions involving goods, but currency and central bank reserves play an important part in the clearing and settlement of private money returned for redemption.Received: 5 May 2003, Revised: 1 December 2003JEL Classification Numbers: E4, E5.The author thanks seminar participants at the Federal Reserve Bank of Richmond and Duke University, conference participants at the Texas Monetary Conference at U.T.

市场风险与信用风险:风险管理中存在的悖论

利率、汇率波动的加剧,使金融衍生市场的风险成为影响金融体系稳定运行的最重要因素之一。在金融风险定价理论和资产组合技术的支持下,金融衍生工具已成为防范基础性金融风险的有效工具。但金融衍生工具在用于金融风险管理中也存在市场风险、信用风险、流动性风险等基本金融风险。不仅存在着市场风险与信用风险的替代性,还存在着加大金融风险总量的可能。金融风险管理的实质是寻求风险损失与风险收益的平衡。
